COMBINED WATER-HEATER AND RANGE.

SPECIFICATION forming part of Letters Patent No. 523,277, dated July 17,1894.

Application filed March 81, 1894. Serial No. 505.844. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC N. HALL, residing at Mediapolis, in the countyof Des Moines and State of Iowa, have invented a new and ImprovedCombined Water-Heater and Range, of which the following isaspecification.

My invention relates to a combined water heater and range and it hasprimarily for its object to provide a heater of this kind of a simpleand inexpensive construction which can be set up in a kitchen and usedas a range for ordinary purposes and as a means for heating water andcausing a circulation thereof through the heating pipes in the severalrooms.

Furthermore it has for its object to provide a heating means of thiskind in which the combustion chamber and water pipes are so arrangedthat a large quantity of water can be heated and forced up through thepipes with a small outlay of fuel, and in a very effective manner.

With other objects in view, which hereinafter will be referred to, theinvention consists in the novel construction and peculiar combination ofparts, all of which will be first described in detail and then bepointed out in the appended claims, reference being had to theaccompanying drawings, in which- Figure 1 is a vertical section of myimproved heater showing the same adapted for burning hard coal. Fig. 2is a section of the lower portion of the stove showing its combustionchamber constructed to burn soft coal. Fig. 3 is a sectional plan viewtaken on the line 33 Fig. 1.

Referring to the accompanying drawings by letters of reference, Aindicates the body or base portion of the stove which comprises acircular inverted cone shaped combustion chamber B, a grate section 0and an ash pit D. The grate when the heater is adapted to burn hard coalis constructed substantially in the manner shown in Fig. 1, by referenceto which it will be seen that supported centrally on a cross member a isa hollow body E having a cone shaped top 6 and through such body,centrally, is projected a tube 6' which projects above the top 6. Inthis tube is held to rock a shaft F having at its upper end the conicalgrate formed of downwardly inclined grate fingers F, while its lower endhas a shaker or rocker barf adapted to be operated from the outside ofthe base as shown. Projected centrally from the base is a verticalextension or cylinder G, the upper end of which is slightly enlarged ath, in which is held an annular chamber or heater H, fitted about theupper end of the magazine I, which is formed with an annular jacket orspace I to prevent the coal from coking in it andx choking and stoppingthe ready fall of the coal, and such magazine extends to the top of thecylinder G, the feed opening G of which is held closed by the lid 9 asshown.

Within the space I between the magazine and the cylinder G is held aseries of water or circulating pipes J, J, which each consists of avertical member j extended the full length of the space I an outwardlyand downwardly curved portion j, inwardly inclined portions 9' arrangedparallel with the sides of the base or combustion chamber, and inwardlycurved portions 7' which connect with the hollow chamber E. e

- It will be noticed that by curving the pipes in the manner shown andmaking them with a long vertical extension practically without a singlesharp bend or curve, such arrangement while forming substantially a firebox or fuel holding pot at the lower end, will, owing to the fact thatthey are free from angles, serve to cause the water to rise more freelyand with a much greater force or momentum. It will also be noticed thatby forming the several pipes each of a single member entirely free fromjoints, the trouble heretofore had in making heaters with straightupright pipes having joints, which through unequal expansion breakloose, will be avoided.

K indicates the feed water pipe which opens into the chamber E and L theoff-take'hot rco is cut off as at B to reduce the width sufficient toallow the said heater being passed through a narrow doorway and therebyavoid the necessity of taking it apart to get it in a house. The cut of?portion B has a valve opening b over which is adapted to be fitted apendent extension 0 of an oven held on the top of the base portion ofthe stove. This oven it will'be noticed has acombustion chan1- ber 0surrounding the baking chamber 0 which chamber 0' has an off take flue Pwhich discharges into the main off take flue, and a valve or cut oif Pin its bottom whereby the heat from the stove proper to the oven can beregulated, it being understood that when the oven is used the valve b isto its open position.

For compactness and to allow a free discharge of the ashes the lowerends of the pipes J are connected with the chamber E alternately oneabove the other as shown.

lVhen soft coal is used the combustion chamber of the stove isconstructed as shown in Fig. 2. In this form the central chamber E isdispensed with and an annular chamber E of adiameter similar to theheater K, with such chamber E the pipes J connect and the feed pipe Kdischarges. The grate is formed conical as before stated the bars beingarranged on a rocker bar and spaced to allow clinkers and hard stones topass through.

From the foregoing description taken in connection with the drawings, itis thought the complete operation and advantages of my improvement willreadily appear. It will be observed that the construction is of such anature that a single stove will serve to heat the entire house and alsoserve as a cooking range, in a quick and economical manner.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An improved heaterof thekinddescribed, comprising an upper waterdistributing chamber, a series of pendent feed pipes, bent to form afuel holding pot at the lower end, with their ends extended radiallyinward to form a grate portion, and a centrally disposed Water heatingchamber, connecting the ends of the grate portions of the pipes,substantially as shown and for the purposes described.

2. An improved heater of the kind described comprising an invertedconical like body having a central upwardly extended fuel magazine orcylinder, a water distributing chamber held at the upper end of suchmagazine, a water holding chamber held centrally at the base of the bodyand the feed pipes, connected with the water distributing chamber,passed down on the outside of the magazine into the stove body, andhaving portions curved outwardly under the top of such body, andinwardly curved portions connected with the Water holding chamber andadapted to form a grate portion all arranged substantially as shown anddescribed.

3. An improved heater comprising a main bod y or heating chamber, havingat its base a centrally disposed water receiving chamber, a waterdistributing chamber held above the main body, a series of feed pipesconnecting the water receiving and distributing chambers, arranged toform the fuel holding chamber and grate portion, a rocker stem pro ectedcentrally of the water holding chamber into the fuel chamber havingradial downwardly inclined arms and means for rocking such stem and armssubstantially as and for the purposes described.

4-. In a heater of the character described, the combination with a bodyportion, having a central vertical extension having an oft take at thetop, a magazine having a surround ng jacket, held in such cylinder, adistributing water chamber held in the top of the cylinder, a conicalgrate held in the bottom of the body portion, a water receiving chamberheld under the grate, a series of circulating pipes connected at one endto the water receiving chamber, curvedoutward and inward within the bodyportion to form a fuel pot, and terminating in straight portionsprojected up between the magazine jacket and the cylind er and connectedwith the distributing chamber all substantially as shown and for thepurposes described.

5. In a heater for the purpose described, the combination with thecombustion portion, formed of a circular inverted cone shaped bodyhavinga portion cut off at one end, havin g a heat outlet, a centralmagazine and combustion cylinder surrounding such magazine provided withan oif take, of an oven, having a pendent portion adapted to fit overthe heat outlet in the cut olf portion, and having a combustion chamber,a valve over its inlet opening, a heating chamber, and an off takeconnecting the said oven combustion chamber and the main off take flueall arranged substantially as shown and described.

6.
